I can safely rewrite all the Unix Commands in my initial post using the FIND Command as follows to avoid the Large number of files error:

1) find Inputpath -name '*.pdf' -exec mv -f {} Outputpath +

2 ) find Inputpath -name '*.pdf' -exec cp {} Outputpath +

3) find Inputpath -name '*.[Pp][Dd][Ff]'

4) find Inputpath/* -exec rm -rf {} +

In the 4th commnd above my aim is to delete all subdirectories and files within the Inputpath Directory but not delete the Inputpath directory itself.

Am I correct on all the above?

No. #3 prints a lit of PDF files in Inputpath and its subdirectories when with mixed case spellings of PDF (PDF, PDf, PdF, Pdf, pDF, pDf, pdF, and pdf); the cp and mv in #1 and #2 will only act on PDF files ending in all lowercase letters (pdf). You need to decide whether you need case insensitive spellings of PDF and choose the appropriate pattern consistently based on your data.

It seems strange to me that you want to print the list of files you're working on after you have done #1 or #2.

This whole thread was started because you already know that #4 won't work; expanding Inputpath/* will create an argument list to long for the exec family of system calls to work. If there are no files in and under Inputpath other than PDF files, the easiest thing to do would be:

Code:

rm -rf Inputpath
mkdir Inputpath

ps2pdf13

PS2PDF(1)							    Ghostscript 							 PS2PDF(1)

NAME

       ps2pdf - Convert PostScript to PDF using ghostscript
       ps2pdf12 - Convert PostScript to PDF 1.2 (Acrobat 3-and-later compatible) using ghostscript
       ps2pdf13 - Convert PostScript to PDF 1.3 (Acrobat 4-and-later compatible) using ghostscript

SYNOPSIS

       ps2pdf  [options...] (input.[e]ps|-) [output.pdf|-]
       ps2pdf12  [options...] (input.[e]ps|-) [output.pdf|-]
       ps2pdf13  [options...] (input.[e]ps|-) [output.pdf|-]

DESCRIPTION

       The ps2pdf scripts are work-alikes for nearly all the functionality (but not the user interface) of Adobe's Acrobat(TM) Distiller(TM) prod-
       uct: they convert PostScript files to Portable Document Format (PDF) files.

       The three scripts differ as follows:

       -      ps2pdf12 will always produce PDF 1.2 output (Acrobat 3-and-later compatible).

       -      ps2pdf13 will always produce PDF 1.3 output (Acrobat 4-and-later compatible).

       -      ps2pdf per se currently produces PDF 1.2 output (Acrobat 3-and-later compatible). However, this may change in  the  future.  If  you
	      care  about  the	compatibility  level of the output, use ps2pdf12 or ps2pdf13, or use the -dCompatibility=1.x switch in the command
	      line.

       There are some limitations in ps2pdf's conversion. See the HTML documentation for more information.
